Building from source

Nice project !

Would be interesting to make more complicated chips emulation components (like 65C02 etc) ...

Had some troubles building from source - so leaving for others as reference

sudo apt-get install build-essential cmake qtbase5-dev qtdeclarative5-dev
cd /src && git clone --depth 1 --recurse-submodules https://github.com/aljen/spaghetti
cd /src/spaghetti && mkdir -p build && cd build && cmake .. && make
cd /src/spaghetti/build && mkdir -p packages && ./SpaghettiEditor 

Serialize free id's list

IO properties don't work

Implement undo/redo stack

Build Failed -- Detecting CXX boost::filesystem support -- NOT FOUND

Hello Aljen,

First of all, I wanted to thank you for your contribution with this wonderful project! I've been trying to build from source now for a few days, and I'm facing the typical problems that come along with trying to build a project that was written even just a few years ago, with the most updated versions of everything.

Somewhere along the way, I've run into some problem. I don't know how I got myself into this mess, but after many hours of googling, and no luck anywhere, I've come to asking you for help.

--

The Error I listed in the title has been persistent in pretty much all compilers. MSVC 16, MSVC 17, MinGW, MSYS2. No matter what magic I tried with either CMake or b2 for building Boost, I could not get CMake to see the filesystems library. Everything else seems to load fine, but its this filesystems Boost library that is getting hung up somewhere.

I've been using Boost 1.80.0, and if I'm a complete pinecone and just need to try an older combination of libraries, I'll do what I gotta do.

Like I said, I tried this with multiple compilers and could not get any of them to produce a successful result. I'll admit, I'm somewhat new to Boost, but I've got it working before, with other projects. Just not the filesystems library. I have the files in the correct folder, and it seems to be installed, but CMake just cannot see it.

I'm running Windows 11, with MinGW (TDM-64) as my compiler. Also, I'm using CLion, but I do the same commands from the terminal that CLion does, and it gives the same results. As well as from MinGW command prompt, or Visual Studio Command prompt, etc. No luck...

For reference, I've visited and tried/read several of the following:

https://stackoverflow.com/questions/57870032/cmake-v3-15-3-cannot-find-boost-v1-71-0

I could list some more, but I though I'd just let you know what I'm dealing with, and let you get to it when you have time.

I'm very interested in contributing to this project, it looks like it hasn't had a lot of progress for a while, and there were a couple issues in the queue that I think I could tackle, if I could get the dang project to build. facepalm

Thanks in advance for your help with this, again, I'd love to contribute to the project, and add some of the requested functionalities, but I just need to get the project building!

-John

Modbus support

• others?

Build tutorial request

Hello, I know this is probably an inappropriate place to ask,
but I'm struggling to build this project with visual studio cmake.

Could you maybe include a small tutorial how to do it from start to finish, @aljen?
That would be great so I could finally tinker with your marvellous creation.

Finish packages support

Pneumatic

• Tank element
• Valve

Export as package

Set up CI

• Setup Travis CI
• Setup AppVeyor CI

Events system plugin

Comment node

Separate elements from nodes in libspaghetti

• Got rid of Nodes support in Registry and libspaghetti
• Move it to separate plugin libspaghettinodes?
• Refactor Editor to load Nodes from external plugins

Add Help -> Examples menu

Provide examples of circuits with categories

Simplify & clean project

• Move Node/Element/Registry to spaghetti namespace
• Modernize CMakeLists.txt:
• Get rid of boost
• Implement SharedLibrary
• Detect & use C++ filesystem
• Set flags per target
• Export/install library
• Add support for CPack

Can't install due to incomplete privileges

I've been trying to install this excellent tool for the last 2 weeks. I have built the INSTALL solution, but I get a std::bad_alloc error when the addElement function is called. I'm new to the C++ build process.

I am desperate to make this tool work because it looks perfect for my application. I'm on a work computer so I cannot give it unfettered access to everything.

Can someone please share an portable version so I can just click and run? Please.

Support drag & drop .package

Move IO to other edges

Allow linking elements backwards in the x-direction

Hey, what a beautiful piece of software. Thank you so much. This seems to me to be so much more elegant and capable than most other tools with a really rich selection of objects and a modern simple user interface.

I'm trying to draw the following logic circuit:

I've struggled a bit -- partly because it seems difficult to link a node to another node which comes prior in the x direction. The routing just doesn't appear to work for this case.

Here's my best effort:

You can see the loop back in the top right corner of the first diagram can't be adequately represented in spaghetti without the edges overlapping the nodes or making other compromises.

Renaming IOs doesn't work

Package::{pause,resume}DispatchThread not working

Switch to .circuit instead of .package

Move selected nodes to new package/export as package

Manometer node

Cleanup

• Move headers for all elements to <spaghetti/elements>
• Fix sparsepp as it's not being copied to <spaghetti/vendor>
• Update vendor libs

Race condition in Package::open & Package::dispatchThreadFunction
